Emerging functions of mammalian mitochondrial fusion and fission [PDF]
, 2005 Mitochondria provide a myriad of services to the cell, including energy production, calcium buffering and regulation of apoptosis. How these diverse functions are coordinated among the hundreds of mitochondria in a given cell is largely unknown, but is ...

eLife, 2017 MFN2 encodes mitofusin 2, a membrane-bound mediator of mitochondrial membrane fusion and inter-organelle communication. MFN2 mutations cause axonal neuropathy, with associated lipodystrophy only occasionally noted, however homozygosity for the p ...

Broad activation of the ubiquitin-proteasome system by Parkin is critical for mitophagy [PDF]
, 2011 Parkin, an E3 ubiquitin ligase implicated in Parkinson's disease, promotes degradation of dysfunctional mitochondria by autophagy. Using proteomic and cellular approaches, we show that upon translocation to mitochondria, Parkin activates the ubiquitin ...

Mitofusin 1 and mitofusin 2 are ubiquitinated in a PINK1/parkin-dependent manner upon induction of mitophagy [PDF]
Human Molecular Genetics, 2010 Mitochondrial dysfunction and perturbed degradation of proteins have been implicated in Parkinson's disease (PD) pathogenesis. Mutations in the Parkin and PINK1 genes are a cause of familial PD. PINK1 is a putative kinase associated with mitochondria, and loss of PINK1 expression leads to mitochondrial dysfunction, which increases with time.

Back to The Fusion: Mitofusin-2 in Alzheimer’s Disease [PDF]
Journal of Clinical Medicine, 2020 Mitochondria are dynamic organelles that undergo constant fission and fusion. Mitochondria dysfunction underlies several human disorders, including Alzheimer’s disease (AD). Preservation of mitochondrial dynamics is fundamental for regulating the organelle’s functions.

Disruption of fusion results in mitochondrial heterogeneity and dysfunction [PDF]
, 2005 Mitochondria undergo continual cycles of fusion and fission, and the balance of these opposing processes regulates mitochondrial morphology. Paradoxically, cells invest many resources to maintain tubular mitochondrial morphology, when reducing both ...

Mitofusins: Mighty Regulators of Metabolism [PDF]
Cell, 2013 Mitochondria are central regulators of cellular metabolism but how their function in a subset of cells affects whole-body energy balance is less understood. Two studies in this issue of Cell identify how diet-dependent modulation of mitochondrial fusion in specific neuronal circuits impact the metabolic status of an animal.

Burst mitofusin activation reverses neuromuscular dysfunction in murine CMT2A
eLife, 2020 Charcot–Marie-Tooth disease type 2A (CMT2A) is an untreatable childhood peripheral neuropathy caused by mutations of the mitochondrial fusion protein, mitofusin (MFN) 2.

Structure and function of bacterial dynamin-like proteins [PDF]
, 2012 Membrane dynamics are essential for numerous cellular processes in eukaryotic and prokaryotic cells. In eukaryotic cells, membrane fusion and fission are often catalyzed by large GTPases of the dynamin protein family. These proteins couple GTP hydrolysis
